Investors & landlords

Your profile indicates you are using the online version of TurboTax Deluxe and I doubt you will be able to get the transaction ported to Part II of Form 4797 with that version.

If you were (or are) using TurboTax Self-Employed or TurboTax Home & Business, you can get to that section of Form 4797 through the Business Income and Expenses section.

You need to click the Start (or Update) button to the right of Special Situations and then check the box as shown in the screenshot below. From that point you will enter an asset description and select Ordinary income asset from the dropdown menu. Of course, you will enter your cost basis as zero.
